Tetra Whisper EX Filter Cartridge Large 2pk**

Replacement Cartridges for Whisper EX Large Filter
The new EX Series Filtration Systems take the ease of maintaining an aquarium to a whole new level. From its innovative use of Timestrip¨ technology to the new patented carbon filter carrier, every new feature in this system has been designed with simplicity and convenience in mind. This is truly the intuitive filtration system.
Simple set-up – it is ready to go right out of the box, you only have to adjust the intake tube to the proper depth and plug it in.
Simple operation –

· Timestrip tells you when to change the carbon filter

· Access door stays in place while changing filter

· Carrier for filter keeps your hands away from dirty cartridges and virtually eliminates drips on floors and furniture

· Submerged motor requires less maintenance than previous external models
Scientifically engineered water flow –

· Rounded shape creates circular flow that prevents sediment from forming in bottom of system chamber.

· Water is forced through new multi-density carbon filters that suspend the carbon for greater contact and improved filtration.

· New non-clogging bio-scrubber forces all water to flow over its entire surface. No bypass is allowed. The bristle design provides more surface area for biological conversion of toxic ammonia to harmless compounds.
